[Sheepdog] Dividing objects across disks

[Fernando Frediani (Qube)]

If a server have multiple IP aliases on the same interface or multiple interfaces how can the process ensure it will always get the same IP to be its zone if eventually these IPs are add/removed ? Perhaps something more static to the node ?

That's true. Of course, you then can't use zones in the way they were originally intended (e.g. to ensure one copy of the data in data centre A and another in data centre B), unless there are zones of zones :-)
